Firefox Community Forum

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

For a few days, for unknown reasons I have been unable to access my blog..."Kitchen Connection". This has never occurred before, and it is very annoying. I have been blogging for many years.

Your assistance in this matter would be appreciated. Thank you in anticipation.

I've tried submitting the above a few times...and for whatever reason, it has not gone through to you, it would appear.

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

Hello, vinted.com/ vinted.co.uk has been throwing me all sorts of strange errors and security concerns over the past 4-5days. Any ideas? Thanks for your help!

I use FF on desktop. Recently, I've run into a problem. My desktop browser will not load any pages... except Youtube. Youtube loads just fine, I can open a video or browse channels or community pages normally. I have fully reset my browser, reinstalled it, and disabled extensions. Other browsers on my PC will work normally. I have very few extensions: Sponsorblock for Youtube, uBlock Origin, and Facebook Container, that's it. I am not using a proxy or VPN. Troubleshoot mode did not fix the issue. I'm not the most tech savvy, so I apologize if I missed anything here.

Any insight is appreciated. Thanks!

When I try to compose a new email, or reply to one, the pane opens to compose the email, but immediately closes before I can enter anything, reverting back to the Inbox. A new, empty draft gets created. But there is no way I can create a new email. Problem does not occur on other browsers. If I open a "New Private Window" and sign in to Outlook, I can then create the email there, but after a while the same problem occurs in that window too. Tried clearing Firefox cache temp files and cookies, but that did not resolve the problem. Using web based Outlook, Windows 10. Firefox is up to date.

Any suggestions?

Trying to connect to yahoo mail (currently.com) and keep getting error messages. All other websites on firefox work.

Some web sites have begun to not work with Firefox browser on Windows 7 64 bit. Is there anyway to get a version of Firefox that that will get me back to working as well as before 4/9/2025. My Firefox web browser says it is fully updated. If Firefox browser is to no longer work with Windows 7, can you suggest a simple browser that can be downloaded for Windows 7 and tell me where and how to download it?

I received a dialogue window telling me that the browser has a problem displaying the webpage. The problem is being worked on and to try again in a few minutes. I refreshed the webpage about ten minutes later and the webpage is displayed as a blank white page. The web address for that webpage is displayed in the web address bar.

Dear Mozilla, your browser has a small error. I want to talk to someone on Facebook who I talk to often, Firefox allows it. For those I rarely talk to, when I put the cursor on the phone icon, it says that it is not supported. I think this is a bug. Therefore, I have to switch to another browser to talk to someone who rarely talks. Please fix it

A number of important (to me), websites (pension and wages) ask for login details, including password, pin and in some cases using 2FA, will not still allow me access. I have tried changing the passwords etc. However, this seems only to allow access one time only. I am entering the passwords correctly and other info but I can not consitantly access the web pages. I do not use google or Bing search, only Firefox and Duck Duck Go. The last time I was able to use the passwords etc freely was around mid December 2024. I have searched for probable cause and remedy but all to no avail. If I try to access on my iPhone or tablet I can access some but not all. I did have Dashlane on my PC and laptop but have since deleted it. It was not on phone or tablet.

Any advice or help please?
